By Robin Emmott BRUSSELS (Reuters) - The prime surviving suspect in the Paris attacks may have been plotting more operations with the help of a weapons cache and a network of associates, Belgium's foreign minister said on Sunday. Didier Reynders, speaking two days after the capture of Salah Abdeslam, said the suspect's first statement to a magistrate in Brussels suggested further attacks were planned. "He was ready to restart something from Brussels," Reynders told a think-tank event.
